Moving Generic Associated Channel (G-ACh) IANA Registriesto a New Registry
Abstract
RFC 5586 generalized the applicability of the pseudowire Associated
Channel Header (PW-ACH) into the Generic Associated Channel G-ACh.
However, registries and allocations of G-ACh parameters had been
distributed throughout different, sometimes unrelated, registries.
This document coalesces these into a new "Generic Associated Channel
(G-ACh) Parameters" registry under the "Multiprotocol Label Switching
Architecture (MPLS)" heading. This document updates RFC 5586.
This document also updates RFCs 6374, 6378, 6427, and 6428.
Status of This Memo

RFC 7214 Creating G-ACh registries May 2014
Further, the "Pseudowire Associated Channel Types" registry is
renamed to "Generalized Associated Channel (G-ACh) Types (including
Pseudowire Associated Channel Types)" to make its generalized status
explicit, and it is moved into the newly created registry.
Additionally, RFC 6374 [RFC6374], RFC 6378 [RFC6378], RFC 6427
[RFC6427], and RFC 6428 [RFC6428] specify allocations within the
G-ACh that are now moved into the new registry.
With respect to where to find these IANA registries, the RFCs listed
above are updated as indicated in Section 3; however, the registries
themselves are not changed (with the exception of one being renamed).
They are moved unchanged to the new registry.
2. IANA Considerations
IANA has added this document as a reference for each registry that
has been moved or renamed as a result of actions requested by this
document.
IANA has replaced all the relocated registries with pointers to the
new URL or with a redirect.
2.1. Creation of a New Generic Associated Channel (G-ACh) Parameters IANA Registry
IANA has created a new "Generic Associated Channel (G-ACh)
Parameters" registry. This is the common registry that will include
all the registries being moved in Sections 2.2 and 2.3.
2.2. Renaming and Moving the Pseudowire Associated Channel Types Registry
This document renames the "Pseudowire Associated Channel Types"
registry [IANA-PWE3] to "MPLS Generalized Associated Channel (G-ACh)
Types (including Pseudowire Associated Channel Types)". This
registry has been moved and included in the "Generic Associated
Channel (G-ACh) Parameters" registry created in Section 2.1 because
any additional registries are dependent upon the Associated Channel
Header Type.
At the time of publishing this document and moving the registry, the
following RFCs have G-ACh Types allocated: [RFC4385], [RFC5586],
[RFC5718], [RFC5885], [RFC6374], [RFC6378], [RFC6426], [RFC6427],
[RFC6428], [RFC6435], [RFC6478], and [RFC6671].
